Description

Technical Field

[0001] This utility model belongs to the field of spirulina harvesting technology, and specifically relates to a traditional raceway pond spirulina harvesting device. Background Technology

[0002] Spirulina is a microalga with extremely high nutritional value and economic benefits, and it is widely cultivated in open raceway ponds. In this cultivation model, once the spirulina biomass reaches a certain concentration, the algal solution needs to be promptly extracted from the pond and harvested for processing to obtain algal sludge or powder. The core of the harvesting process lies in separating a large amount of water from the diluted algal solution, thereby concentrating the algae. This process is typically accomplished using specialized spirulina harvesting equipment.

[0003] Traditional harvesting methods involve using a water pump to extract spirulina from the pond and separate it at a filter screen. The water then flows back into the cultivation pond, leaving spirulina and other impurities on the filter screen. This method results in low-purity spirulina, and the pumping process can damage the spirulina cells, causing nutrient loss. To improve harvest purity, centrifugation can be used for dehydration. While this method is highly efficient, the equipment is expensive and energy-intensive, and the high-speed centrifugal force can damage the spirulina's activity, affecting product quality.

[0004] Therefore, in order to improve the collection efficiency and purity of spirulina and avoid damage to spirulina during the collection process, it is urgent to design a device for collecting spirulina in traditional raceway pools. Utility Model Content

[0023] Example like Figures 1 to 3 As shown, a conventional raceway pond spirulina harvesting device includes a raceway culture pond 100, which includes a curved section 110, a straight section 120, and a central partition 130. The central partition 130 is located in the middle of the raceway culture pond 100 to separate two straight sections 120. A water-dispersing mechanism 200 is provided at the intersection of the curved section 110 and the straight section 120. The water-dispersing mechanism 200 rotates and moves towards the straight section 120. A spirulina collection mechanism 300 is provided on the straight section 120. The movement of the water-dispersing mechanism 200 creates a pushing water wave towards the straight section 120, which pushes the spirulina floating on the raceway culture pond 100 into the spirulina collection mechanism 300.

[0024] It's worth mentioning that at night, the water remains undisturbed, causing the spirulina to float on the surface while other substances in the algae-cultivating pond settle at the bottom. This phenomenon can be used to collect the spirulina, thus improving its purity. Therefore, this harvesting device utilizes the characteristic of spirulina floating on the water surface at night to harvest it at dawn.

[0025] Preferably, the water-dispensing mechanism 200 includes a mounting base 210, a rotating shaft 220, a dispensing blade 230, a mounting rod 240, a driven wheel 250, a driving wheel 260, a synchronous belt 270, and a drive motor 280. The rotating shaft 220 is mounted on the raceway aquaculture pond 100 via the mounting base 210. The driven wheel 250 is mounted on the end of the rotating shaft 220. The driving wheel 260 is mounted on the output end of the drive motor 280. The synchronous belt 270 is sleeved on the driving wheel 260 and the driven wheel 250. Several mounting rods 240 are evenly distributed along the axial direction of the rotating shaft 220, and the dispensing blade 230 is mounted on the mounting rod 240. The drive motor 280 drives the rotating shaft 220 to rotate, which in turn drives the flipping blade 230 to flip. It is worth mentioning that the flipping blade 230 rotates and flips in the direction of the straight section 120, and the rotation speed of the rotating shaft 220 is 20~30 revolutions / min.

[0026] Preferably, the spirulina collection mechanism 300 includes a collection channel 310, a conveying pipe 320, a collection section 330, and a baffle plate 340. The collection channel 310 is installed on the wall of the straight channel area 120, and the inlet of the collection channel 310 is below the water surface. The conveying pipe 320 is installed inside the pool wall of the straight channel area 120, with one end of the conveying pipe 320 penetrating through the inner pool wall of the straight channel area 120 and communicating with the collection channel 310, and the other end penetrating through the straight channel area 120. The outer wall of the pool is connected to the harvesting section 330. To facilitate the output of the harvested spirulina, the outlet of the conveying pipe 320 is lower than the water surface, and the conveying pipe 320 is connected to the lowest end of the harvesting channel 310 to ensure better output. At the same time, the conveying pipe 330 is inclinedly connected to the harvesting section 330. It is worth mentioning that the conveying pipe 320 is made of PVC, PE, or PP materials. The baffle plate 340 is installed in the straight channel area 120. The baffle plate 340 is positioned 3-5 cm above the water surface, with its bottom surface not contacting the bottom of the pool. The baffle plate 340 can be installed on the straight channel area 120 via a hook, mounting nail, or direct clamping. The baffle plate 340 is tangent to the circumference of the harvesting channel 310. One end of the baffle plate 340 is connected to the inner wall of the straight channel area 120, and the other end is connected to the wall of the intermediate partition 130. The angle between the baffle plate 340 and the direction of the water flow is 60-90°. The baffle plate 340 obstructs and guides the spirulina floating on the water surface. Driven by the water waves, the spirulina can smoothly enter the harvesting channel 310 and be transported to the harvesting section 330.

[0027] In some preferred embodiments, the harvesting unit 330 includes a receiving dish 331, a filter basket 332, a water pumping pipe 333, a drain pipe 334, and a pump body 335. The filter basket 332 is detachably placed on the receiving dish 331. The conveying pipe 320 is connected to the receiving dish 331, and its outlet is located above the filter basket 332. The pump body 335 is connected to the water pumping pipe 333 and the drain pipe 334. The other end of the water pumping pipe 333 is connected to the receiving dish 331, and the other end of the drain pipe 334 is connected to the raceway aquaculture pond 100. The water filtered from the filter basket 332 is redirected back to the raceway aquaculture pond 100 by the pump body 335. This entire spirulina harvesting operation only requires one worker. When the filter basket 332 is full, a new basket can be replaced. The filter basket 332 can be selected with different mesh sizes according to filtration needs.

[0028] In summary, this utility model provides a traditional spirulina harvesting device for raceway pools. It utilizes the characteristic of spirulina floating on the water surface at night to improve the purity of the harvest. At the same time, the water-dispelling mechanism creates water waves on the pool surface, and the spirulina floating on the pool surface is guided into the harvesting channel by the baffle plate. Then, it is transported to the harvesting section through the harvesting channel. After filtration and separation in the harvesting section, the spirulina harvesting is completed. The entire spirulina harvesting operation only requires one worker, which can greatly reduce labor and improve harvesting efficiency and quality.
